[ULPIANUS libro primo de appellationibus. ] §49.3.1.prQuod dicitur eum appellari, qui dedit iudicem, sic accipiendum est, ut et successor eius possit appellari.
[ULPIANUS, On Appeals, Book 1.] The statement that he who appointed a judge is appealed against must be understood in such a way that his successor also can be appealed against.
proinde et si praefectus urbi iudicem dederit uel praetorio, ipse erit prouocandus, qui eum dederit iudicem.
Therefore, even if the prefect of the city or the praetorian prefect has appointed a judge, he himself who appointed the judge will be the one to be appealed to.
§49.3.1.1Ab eo, cui quis mandauit iurisdictionem, non ipse prouocabitur: nam generaliter is erit prouocandus ab eo cui mandata est iurisdictio, qui prouocaretur ab eo qui mandauit iurisdictionem.
In an appeal from one to whom someone has delegated jurisdiction, it is not the delegator himself who will be appealed to; for generally, in an appeal from the person to whom jurisdiction has been delegated, that person must be appealed to who would have been appealed to from the person who delegated the jurisdiction.
